Re: Statistics Tool For Classification/Clustering
Genres are presumably groups. So linear combinations of variables that best separate the genres would be more effectively found by linear canonical variates analysis (aka discriminant analysis).

This will enable you to find linear combinations of variable which best separate the genres.

creating biplots from existing multivariate output
I have a question about creating biplots from *existing* output by PCA, canonical variates analysis (CVA) and correspondence analysis. Am I right in thinking that variable and object scores in correspondence analysis are scaled to the same space and so require no further treatment for producing biplots? Where can I find a clear account that would help me calculate biplot values from existing output, bearing in mind (a) the various definitions of biplots, and (b) the various treatments that different packages give to PCA and CVA output (e.g. eigenvectors or variable loadings in PCA). = Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at http://jse.stat.ncsu.edu/ =

Re: definition of metric as a noun
The phrase 'the metric' is being used here to signify the type of its class. This is perfectly ordinary usage, with no implication that there is only one member of the class. E.g. The pen is mightier than the sword. On Sat, 22 Sep 2001 03:09:55 GMT, [EMAIL PROTECTED] (Neville X. Elliven) wrote: Herman Rubin wrote: The OED cites the following use of metric as a noun: 1921 Proc.

The reader should not be left hanging with those questions unanswered. This is not bad usage at all. In mathematics, the word metric as a noun refers to a general type of distance, not necessarily the type in common use. It is certainly bad usage, for the following reason: the phrase, the metric, implies that there is *one* metric function on Riemannian geometry, which is false. This reason has nothing to do with distance measure in general, as commonly understood, or otherwise. = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =

Re: Factor analysis - which package is best for Windows?
I can't say whether it any good, let alone the best. But I have just seen the following on an archaeological post. UNESCO has released WinIDAMS 1.0 for 32-bit Windows operating system. WinIDAMS is a freeware software package for numerical information processing and statistical analysis. It provides a complete set of data manipulation and validation facilities and a wide range of classical and advanced statistical techniques, including interactive construction of multidimensional tables, graphical exploration of data and time series analysis. You can find more information at the following url: http://www.unesco.org/idams I have checked the URL. It does offer factor analysis.

KyPlot runs under Windows, is freeware and gives you several factor analysis algorithms to choose from. http://www.rocketdownload.com/Details/Math/kyplot.htm On Wed, 29 Aug 2001 23:59:44 +0100, Aron Landy [EMAIL PROTECTED] wrote: Problem is, SAS costs about $20,000 whereas CVF IMSL come bundled for $800 Aron = Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =
